| 1 | 麦积区苹果种植土壤氮磷钾施肥精准化研究显示文摘苹果种植已成为麦积地区的支柱产业,精准化施肥对苹果产业的发展具有重大影响。在甘肃省天水市麦积区3个种植区选择对苹果种植影响较大的土壤氮(N)磷(P)钾(K)元素,结合2012—2013年调查的树龄、实测土壤NPK量、目标产量,借助于NPK比例法,通过计算机模拟计算,在试验区进行两年试验可知,土壤NPK模拟施肥方式能科学的调整土壤NPK施肥量,并使NPK实测施肥比例与NPK适宜比例误差控制在±10%以内,每667 m2产量相比其他种植区较上年增加了5%~15%;模拟施肥量与苹果树对土壤NPK的需求量、吸收量、地块、树龄、地块土壤肥力、生长季节和土壤性状有密切关系。这为麦积区苹果种植精准施肥提供了科学依据和技术支撑。 | 闫秀婧 汪浩然 虎保成 侯正阳 徐晴 Timo Tokola | 2015 | 湖北农业科学2015，54，19： | 2 |

| 9 | On the potential to predetermine dominant tree species based on sparse-density airborne laser scanning data for improving subsequent predictions of species-specific timber volumes显示文摘Background:Tree species recognition is the main bottleneck in remote sensing based inventories aiming to produce an input for species-specific growth and yield models.We hypothesized that a stratification of the target data according to the dominant species could improve the subsequent predictions of species-specific attributes in particular in study areas strongly dominated by certain species.Methods:We tested this hypothesis and an operational potential to improve the predictions of timber volumes,stratified to Scots pine,Norway spruce and deciduous trees,in a conifer forest dominated by the pine species.We derived predictor features from airborne laser scanning(ALS) data and used Most Similar Neighbor(MSN) and Seemingly Unrelated Regression(SUR) as examples of non-parametric and parametric prediction methods,respectively.Results:The relationships between the ALS features and the volumes of the aforementioned species were considerably different depending on the dominant species.Incorporating the observed dominant species inthe predictions improved the root mean squared errors by 13.3-16.4%and 12.6-28.9%based on MSN and SUR,respectively,depending on the species.Predicting the dominant species based on a linear discriminant analysis had an overall accuracy of only 76%at best,which degraded the accuracies of the predicted volumes.Consequently,the predictions that did not consider the dominant species were more accurate than those refined with the predicted species.The MSN method gave slightly better results than models fitted with SUR.Conclusions:According to our results,incorporating information on the dominant species has a clear potential to improve the subsequent predictions of species-specific forest attributes.Determining the dominant species based solely on ALS data is deemed challenging,but important in particular in areas where the species composition is otherwise seemingly homogeneous except being dominated by certain species. | Janne Raty Jari Vauhkonen Matti Maltamo Timo Tokola | 2016 | Forest Ecosystems2016，3，2： | 1 |
